AP HUG Unit 1 Flashcards
(44 cards)
Reference Maps
show the whole world or sections of it; used more for navigation or finding places
Thematic Maps
show one certain theme; uses colors over the world, or dots– not traditional images that look like the world
Absolute Distance/Direction
the precise distance/direction/location– most common system to determine this is the global grid of longitudinal and latitudinal lines
Relative Distance/Direction
a description of distance/direction/location of something in relation to other things–not precise–mercator projection is bad for relative distance
Clustered
high density, very close together
Dispersed
low density, spread far apart
Map Projections
show the world or a country or other area using a flat map that has been distorted at least slightly–is not completely accurate because the world is actually round
Distortion
the shape, area, distance, or direction (SADD) has been changed in some way to put an area that is rounded onto a flat surface
Geographic Data
information about the land, cities, populations, and any number of other things that can be shown on a map
GIS
computer system used to hold + display information in layered maps
Satellite Navigation Systems
GPS (global positioning system) satellites constantly send information about where they are in relation to the earth, and where places are in relation to them. When this data is put onto maps it can be used for navigation on phones, and physical maps with the satellite images and information on them
Remote Sensing
images of the land and other features gathered by airplanes, satellites, and drones using cameras and other techniques
Online Mapping Visualization
Maps that can be seen online, and are used to analyze data, and find patterns
Field Observations
information that is found by people out in the world, instead of research done mainly at a computer, or in a library getting information from books
Census Data
the information gathered from people in the census done every 10 years (in USA). –the census is so we know how many people live in the USA, as well as some other information
Satellite Imagery
satellites are always flying around the earth and they send pictures to stations in various locations. These pictures are collected to make maps, and to look closely at places around the world
Using Data at Different Scales
scales are when different amounts of the world are shown, so using data on different scales can mean looking at data within a state, and also looking at the same data in the whole country
Absolute Location
never changes, latitude/longitude or a house address–its unique to that place
Relative Location
in relation to other places–helps understand significance of the place
Space
area between two+ things
Place
“a unique location”–a point in space
Flows
how different places interact
Distance Decay
if two places are far apart, there will be less of a flow between them–less interaction the farther apart they are
Time-Space Compression
if it only takes a short amount of time to get from one place to another, they feel close – the longer it takes to get to a place, they farther apart they feel
